Bob Lock
Bob Lock changes how the held item moves when the player walks, turning vanilla view bobbing into a smoother hand-lowering effect on Fabric.
What it does
Bob Lock swaps out the stock view bobbing for a newer hand-lowering motion and stops the camera from shaking as the player walks. Its author describes it as a lightweight redesign of the view bobbing experience, and the changes apply only on the client, so servers need nothing installed. The code is released under the CC0 1.0 Universal license, which places it in the public domain, and the source code is publicly available.
Installation requires Fabric Loader and Fabric API, and the mod also lists Cloth Config API as a dependency for its settings. Bob Lock is published for Fabric only, with a single release file for each of four game versions: 1.20.1, 1.21.4, 1.21.8 and 1.21.11. The latest file, 1.1.0+1.21.4, was posted on 2026-01-13, one day after the first release on 2026-01-12.
Key features
Hand-lowering bob
The held hand dips and rises with each step instead of following the older vanilla bobbing curve.
Screen shake removed
Camera shake while moving is eliminated, so the view stays steady during walking and running.
Custom hand animation
The hand motion is tuned for a smoother feel, and the effect can be adjusted through the mod's options screen.
Vanilla-friendly design
The mod keeps the rest of the game unchanged and only alters the bobbing motion of the view.
Compatibility
Latest build for each game version and loader.

Use cases
Players who dislike view bobbing
Players who find vanilla view bobbing distracting can use Bob Lock to keep the camera steadier while exploring.
Modpacks with Fabric
Modpack builders on Fabric can add Bob Lock as a client-side visual option, since it changes nothing on the server.
Who it’s for: Players on Fabric who want a calmer hand and camera motion while walking, sprinting or riding. The mod suits single-player and multiplayer clients alike, as only the client runs it.
